Product description:Cats are entertained by this toy, although they dont seem to be fooled into thinking its a real mouse/rat.The toy gives your cats something to think about - something to occupy us together.Suggest to use it for 10 or 15 minutes at a time, so my cats dont get bored with it.So far, the batteries seem to last through a fair number of sessions of such play.Overall, this toy provides a good amount of fun, and seems to be the only thing of its kind on the market.NOTE:The toys remote controlled movements are too unnatural.
